CHARGING SYSTEM
Measure battery current leakage.
Check the regulator rectifier.
·Battery is failing
·Open circuit in wire harness.
·Poorly connected coupler.
·Shorted harness wire.
·Faulty ignition switch.
·Faulty regulator rectifier.
·Check the charging coil of theA.C
generator.
·Faulty regulator rectifier.
·Faulty battery.
Inspect the charging voltage.
Check the voltage between the battery line and
ground wire of regulator rectifier.
Check the resistance of the charging coil at
the charging coil line of regulator rectifier
coupler.
Check the regulator rectifier.
